WHEEL.

Application led June 24,

Be it known that LLoiiis H. PERLMAN, a citizen -of the United States, residing at New York, in the county of New l ork and State of-New York, have invented certain new and useful Improvements in lVheels; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enablel others skilled in the art to which it appeitains to make and use the same.

In the art of automobile wheels and more particularly in that branch of tlie art in which demountable rims appear, 'difficulty has been experienced from a tendency'to distort the rims and render them out of round by an excessive inthrust of one of the locking wedges before the dia-metrically opposite locking wedge has been inserted, and it is the primary object ofthe present invention to obviate this difficulty.

vWith this and further objects inview, as will in part hereinafter become apparent and in part be stated, the invention coniprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawing,-

Figure l is a transverse section through the peripheral portion of a wheel embodying the features of the present invention, the section being taken on a plane intersecting one of the wedges, the wedge and its bolt being seen in elevation.

Fig. 2 is atop plan view of the parts seen in Fig. l with the demouiitable rim and locking wedge removed.

Fig. 3 is a transverse axial section taken on the plane indicated by line 3 3 of F ig. 2.

Referring to the drawing by numerals, l indicates the wood felly which is, of course, provided with the usual spokes and hub, not seen. A felly band or fixed rim 2 is shrunk, or otherwise fixed, on the felly 1, and is of the type provided with a cylindrical body portion terminating` at its inneredge in a substantially conical stop flange 3. A demountable, tire-carrying rim 4 is adapted to have one of its edges rest on the flange 3 and its other edge supported on the locking wedges 5. Only one of the wedges 5 is shown in the drawing, but it is of course, understood that an, appropriate Vnumber of such wedges is distributed uniformly about the periphery of the wheel Specification of Letters Patent.

Patented Apr. 5, 1921. 1916. serial No. 105,694.

bohdy as is the customary practice. A bolt (i is anchored iii the felly l, for each locking wedge 5 and each of said wedges is provided with a pendent flange 7 apertured to receive said bolt and the flange itself being engaged by a nut 8 threaded onto the bolt 6.

lhe structure as thus far described may be considered conventional in form and may follow the lines of any of the well known tyoes.

t will be perfectly obvious to any one skilled in this art that when an operator has applied the rim 4 and positioned .the several locking wedges 5 and thenbegins to screw up the nuts 8.*if he screws up one nut until this wedge 5 is forced in the ma-Ximum distance, the rim 4 will be distorted and the tightening of the other nuts will not relieve the out of round condition of the rim 4 as the iiithi'ust ofy the several remaining wedges cannot be as great as that of the first wedge. This is true because in the deinountable rim structures in common use today there is no provision made for limiting the extent of inthrust of each of the locking wedges, except such limitation as arises from contact of the pendent flange of the wedge with the edge of the felly band.

The difficulty just mentioned is entirely overcome by the present invention which provides means for limiting the maximum intlirust of any wedge `to substantially that point represented by the final seated position of the demountable rim when all of the wedges are in their final locking conditions.

The character and method of connection of the stop is susceptible of wide variation, but Ifind one very simple and yet efficient means of providing for such stop consists in stamping the material of the felly band 2 outward immediately inthe rear of each wedge 5 producing an outstanding plate 9. To give the plate 9 perfectly straight edges, the material of the felly band 2 is slit along the lines 1 0, lO before the plate 9 is stamped 'entering as far.

- of the felly band 2 represented by the full extent of inward travel of the tip of the wedge 5 when the wedge is moved to that final position represented by the corresponding final'position of all of the vwedges and a uniformi distention of the rim 4 by Sai'd`\ wedges, and by being so located tlie stops 9 serve to'prevent the operator from thrust. ing one of the wedges too bar beneath the demountable rim and thus prevent the next or a diametrically opposite wedge from In this way the stops 9 insure a locationof the several wedges which is uniform both in the matter of tensioning the'rim 4 and of sustaining the same in a perfectly circular condition. Furthermore, the stops 9 have the advantage of providing a dead stop for the several wedges 5 which, upon being reached, enables the operator to discontinue further inward thrust of the nut 8 with the assurancethat the nut has reached its final position and without the liability of stripping the nut.

That edge of felly band 2 provided with flange Sis referred to as the inner edge since it is the edge next to the car body when theY wheel isapplied to an automobile, and the oppositeedge is for the same reason referred to as theouter edge. The direction radially away from the axis ofithe wheel may also properly be called outward and the distinction between that direction and the outer portion of certain parts, referring to the outer faceY of the Wheel, will be apparent from the context.Y

What I claim is 1. The combination with a wheel body and a demountable rim therefor, of wedges for locking the demountable rim on the wheel body and stops disposedin the path of the free Yedges of the wedges for limiting the thrust thereof.

2. The combination with a wheel body adapted to sustain a demountable rim, and

securing means. for the rim compri-sing a. wedge, of a stop outstanding from'theperipheryof the wheel bodyrinto' the'fpath ofl travel of the Wedge. i

' 3.y The combination'with adaptedv to sustain a demountab'le rim, and securing means for `the rim comprising a wedge, of a sto stamped from the material of the wheel body and outstanding from the peri the wedge. .y

L The combination with a Wheel body Vhaving a metallicfelly band provided at "its inner edge with an outstanding stop fiange and a demountable rim having one edge adapted to rest on said flange', of securing means for the'rim comprising a wedge adapted to sustain the other edge of the demountable rim and to itself rest on the outer edge portion of the felly'band, and a stop stamped from theifelly band outward into the path of the wedge in position for limiting the extent of inward movement thereof.

5. The combination with a wheel body having a metallic felly band provided at its inner edge with an 'outstanding stop flange and a demountable rim having one edge' adapted to rest on said flange, of securing means for the rim comprising a wedge adapted to sustain the other edge of the demountable rim and to itself restv on the outer edge por-tion of the felly band, and a stop'stamped from the felly band outward into the path of the wedge in position for limiting the extent of inward movement 'thereof, said stop comprising a plate having a flat edge presented toward the-Wedge.

6. In a wheel structure, the combination with a felly band, a rim adapted to'be demountably positioned on the felly band and securing means for the rim comprising a wedge for locking the rim on the felly band, of means between the felly band and rim for limiting the movement of the wedge.

In testimony whereof I aiiixmy signature in presence of two witnesses.
